The Influence Of Side-Lying Position On Oropharyngeal Swallow Function In At-Risk Infants: An Exploratory Study, Julian White
The Influence Of Side-Lying Position On Oropharyngeal Swallow Function In At-Risk Infants: An Exploratory Study, Julian White
Dissertations, 2020-current
Speech-Language Pathologists (SLP) are the primary healthcare providers responsible for the evaluation and treatment of infant feeding and swallowing disorders. At-risk infants, such as those born prematurely or with certain medical conditions, are more prone to swallowing impairments (i.e., dysphagia). Dysphagia in at-risk infants can have severe consequences such as chronic respiratory symptoms, pneumonia, progressive lung disease, undernutrition, and death. Therefore, it is important to have methods of examining an infant’s swallow functioning that are both safe and accurate. A leading method of evaluating infant swallowing is the Modified Barium Swallow Study (MBS). The works contained within this dissertation document …
Voice Quality As A Predictor Of Dysphagia, Lindsay Griffin
Voice Quality As A Predictor Of Dysphagia, Lindsay Griffin
Dissertations, 2014-2019
The clinical swallowing evaluation (CSE) is a non-instrumental exam that informs speech-language pathologists about a patient’s cognition, readiness for instrumental evaluation, and swallowing symptoms. Because of the common neuroanatomy and physiology of the larynx during voicing and swallowing tasks, coughing or throat clearing after food and drink may indicate swallowing impairment. Also because of the shared mechanisms of the larynx, some clinicians also attribute voice changes after swallowing to dysphagia although many studies to date demonstrate conflicting results on the effectiveness of post-prandial voice assessment. The aim of this study was to assess if dysphonia and/or voice change after swallowing …
Effect Of Biofeedback And Exercise Type On Neural Swallowing Control, Rachel J. Rinehart
Effect Of Biofeedback And Exercise Type On Neural Swallowing Control, Rachel J. Rinehart
Senior Honors Projects, 2010-2019
The clinical efficacy of swallowing exercises is well established in swallowing literature, and biofeedback has been shown to augment cortical hemodynamic response (HDR) during normal swallowing. This study compared HDR during swallowing exercises with and without biofeedback to HDR during normal swallows with and without biofeedback. Healthy adult participants (n=6, mean age=50.83 male=2) were recruited and trained on the following conditions: normal swallowing, swallowing exercise in which a specific physiological target was given (skilled), and swallowing exercises in which no specific physiological target had to be achieved (non-skilled). Biofeedback consisted of submental surface electromyography (sEMG) signals displayed visually. HDR were …
The Effect Of Chronic Obstructive Pulmonary Disease On Swallowing, Jessica R. Torres
The Effect Of Chronic Obstructive Pulmonary Disease On Swallowing, Jessica R. Torres
Senior Honors Projects, 2010-2019
This work is composed of a literature review, research review, and self-reflective essay. The anatomy and physiology of normal swallowing and respiration are reviewed. Additionally, the effect of chronic obstructive pulmonary disease (COPD) on these processes is discussed. The research goal was to determine how lung volume changes adapt the physiology of swallowing in individuals with COPD. The research project was designed and conducted by Teresa Drulia, M.S., CCC-SLP. COPD participants (n=9, mean age=72, 6 male) were compared to older healthy individuals (n=10, mean age= 59, 3 male). Participants completed swallows of 20cc of water at four lung volume conditions: …
The Effects Of Lung Volume On Swallowing In Chronic Obstructive Pulmonary Disease, Teresa C. Drulia
The Effects Of Lung Volume On Swallowing In Chronic Obstructive Pulmonary Disease, Teresa C. Drulia
Dissertations, 2014-2019
Chronic Obstructive Pulmonary Disease (COPD), a respiratory disease that leads to reduced airflow, may result in difficulty swallowing with disease progression. The coordination between the respiratory and swallowing systems decouple and they may experience increased risk of aspiration. This study aimed to determine the effects of lung volume on swallowing in individuals with COPD compared with older healthy. Specifically, the study examined if altering lung volume at the time of the swallow changed swallowing timing, specifically pharyngeal swallow duration, and impacted the respiratory-swallow pattern in individuals with COPD. Measurement of estimated lung volume (ELV), pharyngeal swallow duration, and respiratory-swallow patterning …
The Effect Of Taste On Swallowing Function, Rachel Mulheren
The Effect Of Taste On Swallowing Function, Rachel Mulheren
Dissertations, 2014-2019
This study investigated the effects of taste on swallowing frequency and cortical activation in the swallowing network. The effects of salivary flow and taster status were also examined, along with genetic taster status. The effects of a 3ml bolus compared sour, sour with slow infusion, sweet, water, and water with infusion. Swallowing frequency was significantly higher 0-15 seconds after bolus delivery than 16-30 seconds. Swallowing frequency was higher in the sour conditions, whereas sweet and water did not differ. Functional near-infrared spectroscopy recordings measured changes in blood oxygenation (HbO) in the right and left hemispheres in the premotor, S1 and …
